Topic: Canon 2x and 1.4x mk3 extenders (Read 18388 times)

After buying both of the Canon mk3 extenders I was rather disappointed that they can't be used together.. I thought it was strange as the 2x has the recess which it appears to accommodate the 1.4x but doesn't..

I thought that was crazy after previous versions could, so I thought I can make this work with some duct tape and super glue and nails..

Only joking.. What I did find that with a 12mm extension tube it will allow the 1.4x to sit behind the 2x and work fully...

Also the strange thing was it only picked up the 2x extender so its maximum aperture was 5.6 with both 2x and 1.4x being used.. Plus a bonus it focused to infinity
